What’s New in Allegro PCB Design

Learn more about new features

The board design phase is probably the longest step in new product introduction. Cadence® Allegro® technology helps you to shorten your overall design process by improving individual and team productivity, as well as minimizing rework by bringing more and more of the post-design verification and analysis process into the early design stages.

Allegro PCB DesignTrue DFM Technology

Manufacturability is a fundamental requirement for all your designs. Ultimately, the burden of making a design manufacturable lies with the PCB designer, regardless of who is responsible for manufacturability. Allegro PCB DesignTrue DFM Technology brings more than 2,000 real-time manufacturability rule checks into the design environment, minimizing rework and easing new product introduction. Manufacturing rules cover all aras of PCB fabrication and assembly, including etching, lamination, drilling, plating, solder masks, silk screens, and assembly.

Integrated Design for Fabrication and Assembly Constraints

Manufacturing rules are managed as constraints in the familiar constraints manager, coexisting independently with electrical rules that can have more or less constrictive constraints. Fabrication rules cover outlines, masks, annular ring, copper spacing, silkscreen, holes, backdrilling, and Rigid-Flex features, to name a few. Assembly rules cover outline, component, fiducial, and pastemask checks.

Real-Time DFM Verification

The design canvas shows design for manufacturing (DFM) check violations in real time while designing, because the best time to find and fix errors is now, not later.

Signoff with Confidence

Double-check your DFM rules before signoff with a forced batch check of all rules for your whole design. If you do find something awry, it’s easy to locate and fix in your design.

Actionable Analysis Results for PCB Designers

PCB design is where the science of signal integrity goes from theoretical to real. By bringing actionable analysis results to the PCB designer–in their own environment–the Allegro technology helps designers complete complex designs faster by minimizing post-analysis rework.

Crosstalk Analysis

Easily identify and fix crosstalk issues in your design without being an SI expert. Color-coded and numeric visual cues highlight potentially problematic traces based on the same SigrityTM analysis technology on which experts rely.

Return Path Checks

Easily identify potential return path issues, like crossing a split plane or changing reference planes in real-time while you design, without waiting for the signal integrity engineer to perform analysis and provide feedback.

Return Path DRCs

Save time screening for signals that should have ground or pwoer reference planes but don't. Sometimes, a signal has to cross a split plane. Easily locate and review such deviations from reference planes to ensure you have a complete ground current path.

Impedance Analysis and Vision

Trace segments or parts of a segment are color-coded to show impedance discontinuities based on analysis of where the reference plane is located. Segments are color coded to reflect if the impedance is above, below, or meets the impedance constraints.

Coupling Analysis and Vision

Coupling analysis and vision provides a view of where crosstalk issues may occur. Visual feedback on where higher coupling is occurring and who the aggressor is allows PCB designers to reduce iterations with signal integrity (SI) and power integrity (PI) engineers. Hovering over a trace gives designers detailed information needed to resolve the issues.

The way we collaborate is changing. Everyone is hyper-specialized and spending expert engineering resources where they can make the most impact is one way to make sure your team is running at peak efficiency. Allegro PCB Symphony Team Design Option supports collaborative placement, routing, auto-interactive routing, interactive routing, and shape design to let your team dedicate their time and efforts to get designs done faster through real-time concurrent design collaboration.

Real-Time Concurrent PCB Design Collaboration

Local and dispersed teams can collaborate in real time on a single design and instantly see the changes being made by their teammates. Conflicts are easily avoided by restricting access to an object or objects being edited by a user, dramatically reducing routing time and eliminating the need to merge multiple versions.

Managed Constraint Manager Controls

A single user can have exclusive access to define or update constraints through the constraint manager while all other members continue to design in a constraint-driven flow.

Interactive3D Canvas with Rigid-Flex in Collaborative Environment

Individual engineers and designers can visualize the board in the Interactive3D canvas while other team members continue in their own 2D or 3D canvas.

Your products all have three dimensions. And viewing them in 3D is great, but going back and forth between a 2D design and a 3D visualization feels a lot like trial and error. Don’t just view in 3D; design in 3D with the Allegro Interactive3D canvas.

3D Bending of Flex Material

Bend flex circuitry in your design individually or in groups to verify assembly and fit, and see any collisions that may be happen when folded.

3D Component Placement and Movement

Move and place components in 3D, where it’s easiest to find and fix collisions.

Seamless ECAD/MCAD Collaboration

Product design is a collaborative, often iterative, process between multiple domain experts. It’s a delicate balancing act of maintaining the divide between domains of expertise, but allowing for smooth collaboration.

Advanced Productivity Features

PCB routing is where designers spend the majority of their work day. Productivity, teamwork, and right-the first-time accuracy that Allegro technology delivers are the best ways to shorten your overall design time.

Circuit Reuse Placement and Replication

Create reusable modules of completed circuitry from your library to use in new designs, even on boards with different layer stackups. Applying the module is as easy as copy/paste in a document, but unlike copy/paste, you can manage the module in a library and share it with your whole team.

Route Vision

Always cross your “t’s” and dot your ”i’s.” Clean up and optimize traces for spacing and balance, functionality, and manufacturablity with one quick look, an easy way to improve performance and yield.

Route Optimization

Automatically center individual routes between via and pin channels, and evenly space between multiple routes for clean and neat routes when hugging and shoving.

Route Clearance View

Avoid rejection—visualize object- and route-spacing constraints while routing to know if a trace will fit before attempting.

Schematic-Driven Placement

Speed up design tran sfer and component placementby placing components relative to their location on the schematic.
